I haven&rsquo;t seen an off-the-shelf monitor type that&rsquo;s cheap, but there are some DIY projects based on ion chambers (read: coke can - here&rsquo;s a nice detailed one <a href="http://madscientisthut.com/wordpress/daily-blog/easily-make-a-radiation-detector-ion-chamber/" rel="nofollow" >Make a Cheap and Effective Radiation Detector ( Ion Chamber )</a>. Just don&rsquo;t expect it to perform on the same level, or with the same accuracy, as the commercial products.</p>wololo on COM-08875 - Geiger Tubewololourn:uuid:6dfeb36d-47b1-b0e3-bc6a-56f029f262dc2013-05-08T02:38:27-06:00<p>What do the $10 radon detection kits use then?</p>JLC on COM-08875 - Geiger TubeJLCurn:uuid:ee79c9a5-deb4-c23e-14f0-b86074647ea32013-02-13T14:24:08-07:00<p>Gotta low Bob Lazar!</p>Customer #339809 on COM-08875 - Geiger TubeCustomer #339809urn:uuid:2d624f7b-dd9a-c1ee-618f-ebb582b8d6fb2012-12-14T08:17:05-07:00<p>712!

Needless to say we can&rsquo;t exactly ship radioisotopes all over the place.</p>Customer #167681 on COM-08875 - Geiger TubeCustomer #167681urn:uuid:3a33c2db-492e-1a7b-399e-d986b79018412011-06-24T10:48:56-06:00<p>You guys ever thought about selling a low dose radiation source to go with this guy?</p>Customer #153195 on COM-08875 - Geiger TubeCustomer #153195urn:uuid:c58a5fcc-9319-ab42-5e9f-f1b6bd475b5f2011-06-14T06:30:16-06:00<p>Hi Manuel,<br/>
I would like to hear more about this (spectroscopy)&hellip;<br/>

It shows a graph for sensitivity to Gamma radiation, but doesn&rsquo;t include one for alpha or beta radiation.</p>EvanTeitelman on COM-08875 - Geiger TubeEvanTeitelmanurn:uuid:5d07eafe-d747-4b51-6417-52833cce03572010-12-23T20:00:56-07:00<p>I wouldn&rsquo;t trust anything off eBay if I were you.</p>EvanTeitelman on COM-08875 - Geiger TubeEvanTeitelmanurn:uuid:68a02744-5cde-7485-433e-e41b671b43792010-11-07T18:11:08-07:00<p>It would detect radon gas.

This Geiger tube cannot detect alpha particles, only beta and gamma radiation. You need a Geiger tube with a mica window to detect alpha particles.</p>NeuroFuzzy on COM-08875 - Geiger TubeNeuroFuzzyurn:uuid:9e7e072a-ecb2-62f3-3610-98f1674038482009-12-25T18:53:16-07:00<p>It could detect the radiation from radon gas, and it might be possible to figure out that the gas was radon based on the radiation.</p>99guspuppet was puppetboy on COM-08875 - Geiger Tube99guspuppet was puppetboyurn:uuid:aaf68072-3d8a-641b-2421-3d41968e6a9e2009-10-25T14:26:59-06:00<p>Would this detect radon gas ?<br/>

Too many toys. Too many fun things to play with. Not enough time - and certainly not enough money.<br/>
You are making my wife very unhappy :)<br/>

This window is for detection of alpha and beta particles. The window will appear to be slightly concave as the pressure in the tube is less than atmospheric (~0.1 Atm). The window is extremely fragile, touching it will likely convert your tube to an ornament, wasting your $94!<br/>

With the spectrum you can identify the element emitting the radiation. To detect gamma radiation I would use a scintillator (Which I actually have).</p>robostork on COM-08875 - Geiger Tuberobostorkurn:uuid:3f770bd2-68c9-f1b4-a33b-ec8ed57e09382009-10-07T20:20:07-06:00<p>Thanks for the project ideas</p>kofs on COM-08875 - Geiger Tubekofsurn:uuid:f000c31f-8440-9f22-d6f6-5d0ae2bdaf392009-10-07T14:01:47-06:00<p>well, its a sensor for detecting ionizing radiation. you need one if you want your project to be able to detect gamma rays! maybe you want to make sounds based off of cosmic rays, or need random data for cryptography. im sure a google search would find plenty of other projects involving them.<br/>
its a little pricey at 90 bucks though, i have a complete &lsquo;modern&rsquo; russian geiger counter next to me that i got off ebay for 15 bucks. it was even calibrated, though the papers are in Cyrillic</p>robostork on COM-08875 - Geiger Tuberobostorkurn:uuid:68840cf1-03d8-4dc8-ba19-4211942bde3f2009-10-07T12:51:47-06:00<p>This is pretty cool and all,but what is the point?</p>
